Aaron T. Myers commented on HDFS-2863:
--------------------------------------
Thanks for adding the test. A few small comments:
# No need for the "joiner" variable - it's only used once.
# I think "TestFSNamesystem" isn't a very good name for this test, since this
really only tests a very specific part of HA configuration. Perhaps just add
this test case to TestHAConfiguration?
# Since we currently only support a single shared edits dir, the test could be
made more realistic by not configuring several.
> Failures observed if dfs.edits.dir and shared.edits.dir have same directories.
